FIELD OF THE INVENTION

The present invention relates to 1-aryl-5-alkyl pyrazole compounds, ofgeneral formula (I):

wherein:R₁, R₂, R₃, R₄, R₅, R₆, R₇ and p are as defined below; or a salt thereofand the use of these compounds against ectoparasites such as insects,arthropods and acarina.

BACKGROUND OF THE INVENTION

Animals such as mammals and birds are often susceptible to parasiteinfestations. These parasites may be ectoparasites, such as insects, andendoparasites such as filariae and worms.

Domesticated animals, such as cats and dogs, are often infested with oneor more of the following ectoparasites:

-   -   fleas (Ctenocephalides fells, Ctenocephalides sp. and the like),    -   ticks (Rhipicephalus sp., Ixodes sp., Dermacentor sp., Amblyomma        sp. and the like),    -   mites (Demodex sp., Sarcoptes sp., Otodectes sp. and the like),    -   lice (Trichodectes sp., Cheyletiella sp., Linognathus sp., and        the like), and    -   flies (Hematobia sp., Musca sp., Stomoxys sp., Dermatobia sp.,        Cochliomyia sp., mosquitoes (family Culicidae) and the like).

Fleas are a particular problem because not only do they adversely affectthe health of the animal or human, but they also cause a great deal ofpsychological stress. Moreover, fleas are also vectors of pathogenicagents in animals, such as dog tapeworm (Dipylidium caninum), and mayalso transmit pathogens to humans.

Similarly, ticks are also harmful to the physical and psychologicalhealth of the animal or human. However, the most serious problemassociated with ticks is that they are the vector of pathogenic agents,which cause diseases in both humans and animals Major diseases which arecaused by ticks include borreliosis (Lyme disease caused by Borreliaburgdorferi), babesiosis (or piroplasmosis caused by Babesia sp.) andrickettsiosis (also known as Rocky Mountain spotted fever). Ticks alsorelease toxins which cause inflammation or paralysis in the host.Occasionally, these toxins are fatal to the host, such as in the case ofthe Australian paralysis tick, Ixodes holocyclus.

Moreover, mites and lice are particularly difficult to combat sincethere are very few active substances which act on these parasites andthey require frequent treatment.

Likewise, farm animals are also susceptible to parasite infestations.For example, cattle are affected by a large number of parasites.Likewise, arthropod pests, such as fleas, lice and ticks, and mitesinfest poultry. A parasite that is very prevalent among farm animals isthe tick genus Boophilus, especially those of the species microplus(cattle tick), decoloratus and anulatus. Ticks, such as Boophilusmicroplus, are particularly difficult to control because they live inthe pasture where the farm animals graze. Other important parasites ofcattle and sheep are listed as follows in order of decreasingimportance:

(a) myiases such as Dermatobia hominis (known as Berne in Brazil),Hypoderma, and Cochlyomia hominivorax (greenbottle); sheep myiases suchas Lucilia sericata, Lucilia cuprina (known as blowfly strike inAustralia, New Zealand and South Africa). These are flies whose larvaconstitutes the animal parasite;(b) flies proper, namely those whose adult constitutes the parasite,such as Haematobia irritans (horn fly);(c) lice such as Linognathus vituli etc.; and(d) mites such as Sarcoptes scabiei and Psoroptes ovis.

The compounds of the invention may also be useful against householdpests including, but not limited to, cockroach, Blatella sp., clothesmoth, Tineola sp., carpet beetle, Attagenus sp. and the housefly Muscadomestica and against Solenopsis invicta (imported fire ants), termites,and the like.

These compounds may further be useful against agricultural pests such asaphids (Acyrthiosiphon sp.), locusts, and boll weevils as well asagainst insect pests that attack stored grains, such as Tribolium sp.,and against immature stages of insects living on plant tissue.

The above list is not exhaustive and other ectoparasites are well knownin the art to be harmful to animals, humans and crops.

Compounds that exhibit a degree of activity against a wide range ofectoparasites including arthopods and insects are known in the art. Onesuch class of compounds is the arylpyrazoles which are referred to, forexample, in U.S. Pat. Nos. 5,122,530; 5,246,255; 5,576,429; 5,885,607;6,010,710; 6,083,519; 6,096,329; 6,685,954; EP 0 234 119 and EP 0 295117 (U.S. Pat. Nos. 5,232,940; 5,547,974; 5,608,077; 5,714,191;5,916,618 and 6,372,774); EP 0 352 944 (U.S. Pat. No. 4,963,575); EP 0780 378 (U.S. Pat. Nos. 5,817,688; 5,922,885; 5,994,386; 6,124,339;6,180,798 and 6,395,906); EP 0 846 686 (U.S. Pat. No. 6,069,157); and WO98/28278.

The arylpyrazoles are known to possess excellent activity againstinsects, such as fleas and ticks. Fipronil is a specific type of1-N-aryl pyrazole that is particularly effective against fleas and ticksand is the active ingredient in Frontline® and Frontline Plus®. Fipronilhas the following chemical structure:

However, ectoparasiticidal agents can vary in their effectiveness to aparticular parasite as well as vary in their cost of production.Moreover, the results of ectoparasiticidal agents may not always besatisfactory because of, for example, the development of resistance bythe parasite to the therapeutic agent, as is the case, for example, withcarbamates, organophosphorus compounds and pyrethroids.

It is known from the literature that hydrazines may react with1,3-dicarbonyl compounds to form pyrazoles. For example, U.S. Pat. No.6,750,230 refers to the synthesis of pyrazoles unsubstituted at the oneposition or substituted by an alkylene group from 1,3-diketones. WO01/32663 refers to the synthesis of pyrazolecarboxylic acid tricycliccompounds. WO 03/057674 refers to the synthesis of4-sulfide/sulfoxidepyrazoles bearing a substituted alkyl group at the1-position, which may be prepared from the reaction of a2-thio-1,3-diketone with a hydrazine (see page 24, Reaction Scheme 1).However, there appeared to be no examples where this 2-thio-1,3-diketonederivative was made directly by reacting a sulfenyl halide reagent with1,3-diketone compounds.

WO 02/058690 and US 2004/0876627 refer to the synthesis of pyrazolesbearing a (2,2,2-trifluoro-1-hydroxy-1-(trifluoromethyl)ethylsubstituent by reaction between a 1,3-diketone and phenylhydrazinebearing the 1-hydroxy-1-(trifluoromethyl)ethyl substituent (Scheme 4,page 11, US 2004/0876627). The synthesis of a specific compound by thismethod,5-methyl-1-[(1-hydroxy-1-(trifluoromethyl)ethyl)phenyl)-1H-pyrazole-3-carboxylicacid ethyl ester is mentioned (US 2004/0876627, pages 23-24, Example 8).However, there appeared to be no examples where a 3,4,5-disubstitutedpyrazole is prepared except in the presence of a 5-amino group or whenall three substitutions are the same (methyl).

Synthesis of 3-ester-4-unsubstituted pyrazoles is also referred to in US2005/00020564 (page 10, Scheme 3).

However, a general problem with obtaining pyrazoles by reactinghydrazines with 1,3-dicarbonyl compounds is the difficulty in preparingcompounds with regioselectivity, as there is competition in the reactionat the different carbonyl groups of the 1,3-dicarbonyl compound

Thus, there is still a need in the art for more effective and rapidlyacting antiparasitic composition for the treatment and protection ofanimals, e.g. mammals, fish and birds, from a wide range of parasites.There is a need in the art for an antiparasitic formulation which iseasy to use on any type of domestic animal, irrespective of its size andthe nature of its coat and which do not need to be sprinkled over theentire body of the mammal, fish or bird. Further, the formulation shouldbe effective for a long period of time thereby reducing the number oftimes it has to be applied.

The composition of the invention can also be in a variety of forms whichinclude, but are not limited to, oral formulations, injectableformulations, and topical, dermal or subdermal formulations.

The composition of the invention may be in a form suitable for oral use,for example, as baits (see, e.g., U.S. Pat. No. 4,564,631), dietarysupplements, troches, lozenges, chewables, tablets, hard or softcapsules, emulsions, aqueous or oily suspensions, aqueous or oilysolutions, oral drench formulations, dispersible powders or granules,syrups or elixirs, enteric formulations or pastes. Compositions intendedfor oral use may be prepared according to any method known in the artfor the manufacture of pharmaceutical compositions and such compositionsmay contain one or more agents selected from the group consisting ofsweetening agents, bittering agents, flavoring agents, coloring agentsand preserving agents in order to provide pharmaceutically elegant andpalatable preparations.

Tablets may contain the active ingredient in admixture with non-toxic,pharmaceutically acceptable excipients which are suitable for themanufacture of tablets. These excipients may be, for example, inertdiluents, such as calcium carbonate, sodium carbonate, lactose, calciumphosphate or sodium phosphate; granulating and disintegrating agents,for example, corn starch, or alginic acid; binding agents, for examplestarch, gelatin or acacia, and lubricating agents, for example,magnesium stearate, stearic acid or talc, the tablets may be uncoated orthey may be coated by known techniques to delay disintegration andabsorption in the gastrointestinal tract and thereby provide a sustainedaction over a longer period. For example, a time delay material such asglyceryl monostearate or glyceryl distearate may be employed. They mayalso be coated by the technique described in U.S. Pat. Nos. 4,256,108;4,166,452; and 4,265,874 (incorporated herein by reference) to formosmotic therapeutic tablets for controlled release.

Formulations for oral use may be hard gelatin capsules, wherein theactive ingredient is mixed with an inert solid diluent, for example,calcium carbonate, calcium phosphate or kaolin. Capsules may also besoft gelatin capsules, wherein the active ingredient is mixed with wateror miscible solvents such as propylene glycol, PEGs and ethanol, or anoil medium, for example peanut oil, liquid paraffin, or olive oil.

The compositions of the invention may also be in the form ofoil-in-water or water-in-oil emulsions. The oily phase may be avegetable oil, for example, olive oil or arachis oil, or a mineral oil,for example, liquid paraffin or mixtures of these. Suitable emulsifyingagents may be naturally-occurring phosphatides, for example, soy bean,lecithin, and esters or partial esters derived from fatty acids andhexitol anhydrides, for example, sorbitan monoleate, and condensationproducts of the said partial esters with ethylene oxide, for example,polyoxyethylene sorbitan monooleate. The emulsions may also containsweetening agents, bittering agents, flavoring agents, and/orpreservatives.

In one embodiment of the formulation, the composition of the inventionis in the form of a microemulsion. Microemulsions are well suited as theliquid carrier vehicle. Microemulsions are quaternary systems comprisingan aqueous phase, an oily phase, a surfactant and a cosurfactant. Theyare translucent and isotropic liquids.

Microemulsions are composed of stable dispersions of microdroplets ofthe aqueous phase in the oily phase or conversely of microdroplets ofthe oily phase in the aqueous phase. The size of these microdroplets isless than 200 nm (1000 to 100,000 nm for emulsions). The interfacialfilm is composed of an alternation of surface-active (SA) andco-surface-active (Co-SA) molecules which, by lowering the interfacialtension, allows the microemulsion to be formed spontaneously.

In one embodiment of the oily phase, the oily phase can be formed frommineral or vegetable oils, from unsaturated polyglycosylated glyceridesor from triglycerides, or alternatively from mixtures of such compounds.In one embodiment of the oily phase, the oily phase comprises oftriglycerides; in another embodiment of the oily phase, thetriglycerides are medium-chain triglycerides, for example C₈-C₁₀caprylic/capric triglyceride. In another embodiment of the oily phasewill represent a % v/v range selected from the group consisting of about2 to about 15%; about 7 to about 10%; and about 8 to about 9% v/v of themicroemulsion.

The aqueous phase includes, for example water or glycol derivatives,such as propylene glycol, glycol ethers, polyethylene glycols orglycerol. In one embodiment of the glycol derivatives, the glycol isselected from the group consisting of propylene glycol, diethyleneglycol monoethyl ether, dipropylene glycol monoethyl ether and mixturesthereof. Generally, the aqueous phase will represent a proportion fromabout 1 to about 4% v/v in the microemulsion.

Surfactants for the microemulsion include diethylene glycol monoethylether, dipropyelene glycol monomethyl ether, polyglycolyzed C₈-C₁₀glycerides or polyglyceryl-6 dioleate. In addition to these surfactants,the cosurfactants include short-chain alcohols, such as ethanol andpropanol.

Some compounds are common to the three components discussed above, i.e.,aqueous phase, surfactant and cosurfactant. However, it is well withinthe skill level of the practitioner to use different compounds for eachcomponent of the same formulation. In one embodiment for the amount ofsurfactant/cosurfactant, the cosurfactant to surfactant ratio will befrom about 1/7 to about ½. In another embodiment for the amount ofcosurfactant, there will be from about 25 to about 75% v/v of surfactantand from about 10 to about 55% v/v of cosurfactant in the microemulsion.

Oily suspensions may be formulated by suspending the active ingredientin a vegetable oil, for example, atachis oil, olive oil, sesame oil orcoconut oil, or in mineral oil such as liquid paraffin. The oilysuspensions may contain a thickening agent, for example, beeswax, hardparaffin or cetyl alcohol. Sweetening agents such as sucrose, saccharinor aspartame, bittering agents, and flavoring agents may be added toprovide a palatable oral preparation. These compositions may bepreserved by the addition of an anti-oxidant such as ascorbic acid, orother known preservatives.

Components which may be employed for the active substances according tothe invention in mixed formulations, for example, known active compoundswhich are based on an inhibition of, for example, acetolactate synthase,acetyl-coenzyme A carboxylase, PS I, PS II, HPPDO, phytoene desaturase,protoporphyrinogen oxidase, glutamine synthetase, cellulosebiosynthesis, 5-enolpyruvylshikimate-3-phosphate synthetase. Suchcompounds, and also other compounds which can be employed, whosemechanism of action is to a degree unknown or different, are described,for example, in Weed Research 26, 441-445 (1986), or “The PesticideManual”, 12th Edition 2000 (hereinbelow also abbreviated to “PM”), TheBritish Crop Protection Council and the Royal Soc. of Chemistry(editors) and literature cited therein.

The compounds of formula (I) can be formulated in various ways,depending on the prevailing biological and/or chemico-physicalparameters. Examples of possible formulations which are suitable are:wettable powders (WP), water-soluble powders (SP), water-solubleconcentrates, emulsifiable concentrates (EC), emulsions (EW) such asoil-in-water and water-in-oil emulsions, sprayable solutions, suspensionconcentrates (SC), dispersions on an oil or water basis, solutions whichare miscible with oil, capsule suspensions (CS), dusts (DP),seed-dressing products, granules for broadcasting and soil application,granules (GR) in the form of microgranules, spray granules, coatedgranules and adsorption granules, water-dispersible granules (WG),water-soluble granules (SG), ULV formulations, microcapsules and waxes.

The formulations mentioned can be prepared in a manner known per se, forexample by mixing the active compounds with at least one solvent ordiluent, emulsifier, dispersant and/or binder or fixative, waterrepellent and optionally one or more of a desiccant, UV stabilizer, acolorant, a pigment and other processing auxiliaries.

These individual formulation types are known in principle and described,for example, in: Winnacker-Küchler, “Chemische Technologie” [ChemicalTechnology], Volume 7, C. Hauser Verlag, Munich, 4th Edition 1986; Wadevan Valkenburg, “Pesticide Formulations”, Marcel Dekker, N.Y., 1973; K.Martens, “Spray Drying Handbook”, 3rd Ed. 1979, G. Goodwin Ltd. London.

The necessary formulation auxiliaries such as inert materials,surfactants, solvents and other additives are also known and described,for example, in: Watkins, “Handbook of Insecticide Dust Diluents andCarriers”, 2nd Ed., Darland Books, Caldwell N.J.; H. v. Olphen,“Introduction to Clay Colloid Chemistry”, 2nd Ed., J. Wiley & Sons,N.Y.; C. Marsden, “Solvents Guide”, 2nd Ed., Interscience, N.Y. 1963;McCutcheon's “Detergents and Emulsifiers Annual”, MC Publ. Corp.,Ridgewood N.J.; Sisley and Wood, “Encyclopedia of Surface ActiveAgents”, Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt,“Grenzflachenaktive Athylenoxidaddukte” [Surface-active ethylene oxideadducts], Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Küchler,“Chemische Technologie” [Chemical Technology], Volume 7, C. HauserVerlag, Munich, 4th Ed. 1986.

Wettable powders are preparations which are uniformly dispersible inwater and which, besides the compounds of formula (I), also compriseionic and/or nonionic surfactants (wetters, dispersants), for example,polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols,polyoxyethylated fatty amines, fatty alcohol polyglycol ether sulfates,alkanesulfonates or alkylbenzenesulfonates, sodium lignosulfonate,sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, sodiumdibutylnaphthalenesulfonate or else sodium oleoylmethyltaurinate, inaddition to a diluent or inert substance. To prepare the wettablepowders, the compounds of formula (I) are, for example, ground finely inconventional apparatuses such as hammer mills, blower mills and air-jetmills and mixed with the formulation auxiliaries, either concomitantlyor thereafter.

Emulsifiable concentrates are prepared, for example, by dissolving thecompounds of formula (I) in an organic solvent, for example butanol,cyclohexanone, dimethylformamide, xylene or else higher-boilingaromatics or hydrocarbons or mixtures of these, with addition of one ormore ionic and/or nonionic surfactants (emulsifiers). Emulsifiers whichcan be used are, for example: calcium salts of alkylarylsulfonic acids,such as calcium dodecylbenzenesulfonate or nonionic emulsifiers, such asfatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcoholpolyglycol ethers, propylene oxide/ethylene oxide condensates, alkylpolyethers, sorbitan esters such as sorbitan fatty acid esters orpolyoxyethylene sorbitan esters such as polyoxyethylene sorbitan fattyacid esters.

Dusts are obtained by grinding the active substance with finely dividedsolid substances, for example talc or natural clays, such as kaolin,bentonite or pyrophyllite, or diatomaceous earth.

Suspension concentrates may be water- or oil-based. They can beprepared, for example, by wet grinding by means of commerciallyavailable bead mills, if appropriate with addition of surfactants, asthey have already been mentioned above for example in the case of theother formulation types.

Emulsions, for example oil-in-water emulsions (EW), can be prepared forexample by means of stirrers, colloid mills and/or static mixtures usingaqueous organic solvents and, if appropriate, surfactants as they havealready been mentioned above for example in the case of the otherformulation types.

Granules can be prepared either by spraying the compounds of formula (I)onto adsorptive, granulated inert material or by applying activesubstance concentrates onto the surface of carriers such as sand,kaolinites or of granulated inert material, by means of binders, forexample polyvinyl alcohol, sodium polyacrylate or alternatively mineraloils. Suitable active substances can also be granulated in the mannerwhich is conventional for the production of fertilizer granules, ifdesired in a mixture with fertilizers.

Water-dispersible granules are prepared, as a rule, by the customaryprocesses such as spray-drying, fluidized-bed granulation, diskgranulation, mixing in high-speed mixers and extrusion without solidinert material. To prepare disk, fluidized-bed, extruder and spraygranules, see, for example, processes in “Spray-Drying Handbook” 3rd ed.1979, G. Goodwin Ltd., London; J. E. Browning, “Agglomeration”, Chemicaland Engineering 1967, pages 147 et seq.; “Perry's Chemical Engineer'sHandbook”, 5th Ed., McGraw-Hill, New York 1973, p. 8-57.

In general, the agrochemical preparations comprise a range selected fromthe group consisting of about 0.1 to about 99% by weight and about 0.1to about 95% by weight, of compounds of formula (I).

The concentration of compounds of formula (I) in wettable powders is,for example, about 10 to about 90% by weight, the remainder to 100% byweight being composed of customary formulation components. In the caseof emulsifiable concentrates, the concentration of compounds of formula(I) can amount to ranges selected from the group consisting of about 1%to about 90% and about 5% to about 80% by weight. Formulations in theform of dusts usually comprise in the range selected from the groupconsisting of about 1% to about 30% by weight of compounds of formula(I) and about 5% to about 20% by weight of compounds of formula (I). Forsprayable solutions comprise a range selected from the group consistingof about 0.05% to about 80% by weight of compounds of formula (I) andabout 2% to about 50% by weight of compounds of formula (I). In the caseof water-dispersible granules, the content of compounds of formula (I)depends partly on whether the compounds of formula (I) are in liquid orsolid form and on which granulation auxiliaries, fillers and the likeare being used. The water-dispersible granules, for example, comprise arange selected from the group consisting of between about 1 and about95% and between about 10% and about 80% by weight.

In addition, the formulations of compounds of formula (I) mentionedcomprise, if appropriate, the adhesives, wetters, dispersants,emulsifiers, penetrants, preservatives, antifreeze agents, solvents,fillers, carriers, colorants, antifoams, evaporation inhibitors, pHregulators and viscosity regulators which are conventional in each case.

The mixtures according to the invention can be applied via the soileither pre-emergently or post-emergently. The mixtures according to theinvention can also be applied via the leaf. The mixtures according tothe invention can be employed for seed dressing. It is also possible toapply the mixtures according to the invention via an irrigation system,for example via the water for irrigation.

When used as insecticides, the active compounds according to theinvention can furthermore be present in their commercially availableformulations and in the use forms, prepared from these formulations, asa mixture with synergists. Synergists are compounds which increase theaction of the active compounds, without it being necessary for thesynergistic agent added to be active itself.

When used as insecticides, the active compounds according to theinvention can furthermore be present in their commercially availableformulations and in the use forms, prepared from these formulations, asa mixture with inhibitors which reduce degradation of the activecompound after use in the environment of the plant, on the surface ofparts of plants or in plant tissues.

The active compound content of the use forms prepared from thecommercially available formulations can vary within wide limits. Theactive compound concentration of the use forms can be from about0.00000001 to about 95% by weight of active compound, preferably betweenabout 0.00001 and about 1% by weight.

The active compounds are employed in a customary manner appropriate forthe use forms.

All plants and plant parts can be treated in accordance with theinvention. Plants are to be understood as meaning in the present contextall plants and plant populations such as desired and undesired wildplants or crop plants (including naturally occurring crop plants). Cropplants can be plants which can be obtained by conventional plantbreeding and optimization methods or by biotechnological and geneticengineering methods or by combinations of these methods, including thetransgenic plants and including the plant cultivars protectable or notprotectable by plant breeders' rights. Plant parts are to be understoodas meaning all parts and organs of plants above and below the ground,such as shoot, leaf, flower and root, examples which may be mentionedbeing leaves, needles, stalks, stems, flowers, fruit bodies, fruits,seeds, roots, tubers and rhizomes. The plant parts also includeharvested material, and vegetative and generative propagation material,for example cuttings, tubers, rhizomes, offshoots and seeds.

Treatment according to the invention of the plants and plant parts withthe active compounds is carried out directly or by allowing thecompounds to act on the surroundings, habitat or storage space by thecustomary treatment methods, for example by immersion, spraying,evaporation, fogging, scattering, painting on, injection and, in thecase of propagation material, in particular in the case of seeds, alsoby applying one or more coats.

The active compounds according to the invention are particularlysuitable for treating seed. Here, the active compounds according to theinvention mentioned above as preferred or particularly preferred may bementioned as being preferred. Thus, a large part of the damage to cropplants which is caused by pests occurs as early as when the seed isattacked during storage and after the seed is introduced into the soil,during and immediately after germination of the plants. This phase isparticularly critical since the roots and shoots of the growing plantare particularly sensitive and even minor damage can lead to the deathof the whole plant. Protecting the seed and the germinating plant by theuse of suitable active compounds is therefore of particularly greatinterest.

The control of pests by treating the seeds of plants has been known fora long time and is the subject of continuous improvements. However, thetreatment of seed entails a series of problems which cannot always besolved in a satisfactory manner. Thus, it is desirable to developmethods for protecting the seed and the germinating plant which dispensewith the additional application of crop protection agents after sowingor after the emergence of the plants. It is furthermore desirable tooptimize the amount of active compound employed in such a way as toprovide maximum protection for the seed and the germinating plant fromattack by pests, but without damaging the plant itself by the activecompound employed. In particular, methods for the treatment of seedshould also take into consideration the intrinsic insecticidalproperties of transgenic plants in order to achieve optimum protectionof the seed and the germinating plant with a minimum of crop protectionagents being employed.

The present invention therefore in particular also relates to a methodfor the protection of seed and germinating plants from attack by pests,by treating the seed with an active compound according to the invention.The invention likewise relates to the use of the active compoundsaccording to the invention for the treatment of seed for protecting theseed and the resultant plant from pests. Furthermore, the inventionrelates to seed which has been treated with an active compound accordingto the invention so as to afford protection from pests.

One of the advantages of the present invention is that the particularsystemic properties of the active compounds according to the inventionmean that treatment of the seed with these active compounds not onlyprotects the seed itself, but also the resulting plants after emergence,from pests. In this manner, the immediate treatment of the crop at thetime of sowing or shortly thereafter can be dispensed with.

Furthermore, it must be considered as advantageous that the activecompounds according to the invention can also be employed in particularin transgenic seed, the plants arising from this seed being capable ofexpressing a protein directed against pests. By treating such seed withthe active compounds according to the invention, certain pests can becontrolled merely by the expression of the, for example, insecticidalprotein, and additionally be protected by the active compounds accordingto the invention against damage.

The active compounds according to the invention are suitable forprotecting seed of any plant variety as already mentioned above which isemployed in agriculture, in the greenhouse, in forests or inhorticulture. In particular, this takes the form of seed of maize,peanut, canola, oilseed rape, poppy, soya beans, cotton, beet (forexample sugar beet and fodder beet), rice, sorghum and millet, wheat,barley, oats, rye, sunflower, tobacco, potatoes or vegetables (forexample tomatoes, cabbage plants). The active compounds according to theinvention are likewise suitable for treating the seed of fruit plantsand vegetables as already mentioned above. The treatment of the seed ofmaize, soya beans, cotton, wheat and canola or oilseed rape is ofparticular importance.

As already mentioned above, the treatment of transgenic seed with anactive compound according to the invention is also of particularimportance. This takes the form of seed of plants which, as a rule,comprise at least one heterologous gene which governs the expression ofa polypeptide with in particular insecticidal properties. In thiscontext, the heterologous genes in transgenic seed may be derived frommicroorganisms such as Bacillus, Rhizobium, Pseudomonas, Serratia,Trichoderma, Clavibacter, Glomus or Gliocladium. The present inventionis particularly suitable for the treatment of transgenic seed whichcomprises at least one heterologous gene orignating from Bacillus sp.and whose gene product shows activity against the European corn borerand/or the corn root worm. It is particularly preferably a heterologousgene derived from Bacillus thuringiensis.

In the context of the present invention, the active compound accordingto the invention is applied to the seed either alone or in a suitableformulation. Preferably, the seed is treated in a state which is stableenough to avoid damage during treatment. In general, the seed may betreated at any point in time between harvest and sowing. The seedusually used has been separated from the plant and freed from cobs,shells, stalks, coats, hairs or the flesh of the fruits.

When treating the seed, care must generally be taken that the amount ofthe active compound according to the invention applied to the seedand/or the amount of further additives is chosen in such a way that thegermination of the seed is not adversely affected, or that the resultingplant is not damaged. This must be borne in mind in particular in thecase of active compounds which may have phytotoxic effects at certainapplication rates.

As already mentioned above, it is possible to treat all plants and theirparts according to the invention. In a preferred embodiment, wild plantspecies and plant cultivars, or those obtained by conventionalbiological breeding methods, such as crossing or protoplast fusion, andparts thereof, are treated. In a further preferred embodiment,transgenic plants and plant cultivars obtained by genetic engineeringmethods, if appropriate in combination with conventional methods(Genetically Modified Organisms), and parts thereof are treated. Theterms “parts”, “parts of plants” and “plant parts” have been explainedabove.

Particularly preferably, plants of the plant cultivars which are in eachcase commercially available or in use are treated according to theinvention. Plant cultivars are to be understood as meaning plants havingnovel properties (“traits”) which have been obtained by conventionalbreeding, by mutagenesis or by recombinant DNA techniques. These can becultivars, bio- or genotypes.

Depending on the plant species or plant cultivars, their location andgrowth conditions (soils, climate, vegetation period, diet), thetreatment according to the invention may also result in superadditive(“synergistic”) effects. Thus, for example, reduced application ratesand/or a widening of the activity spectrum and/or an increase in theactivity of the active compounds and compositions which can be usedaccording to the invention, better plant growth, increased tolerance tohigh or low temperatures, increased tolerance to drought or to water orsoil salt content, increased flowering performance, easier harvesting,accelerated maturation, higher harvest yields, higher quality and/or ahigher nutritional value of the harvested products, better storagestability and/or processability of the harvested products are possible,which exceed the effects which were actually to be expected.

The transgenic plants or plant cultivars (obtained by geneticengineering) which are preferably to be treated according to theinvention include all plants which, by virtue of the geneticmodification, received genetic material which imparted particularlyadvantageous, useful traits to these plants. Examples of such traits arebetter plant growth, increased tolerance to high or low temperatures,increased tolerance to drought or to water or soil salt content,increased flowering performance, easier harvesting, acceleratedmaturation, higher harvest yields, higher quality and/or a highernutritional value of the harvested products, better storage stabilityand/or processability of the harvested products. Further andparticularly emphasized examples of such traits are a better defence ofthe plants against animal and microbial pests, such as against insects,mites, phytopathogenic fungi, bacteria and/or viruses, and alsoincreased tolerance of the plants to certain herbicidally activecompounds. Examples of transgenic plants which may be mentioned are theimportant crop plants, such as cereals (wheat, rice), maize, soya beans,potatoes, sugar beet, tomatoes, peas and other vegetable varieties,cotton, tobacco, oilseed rape and also fruit plants (with the fruitsapples, pears, citrus fruits and grapes), and particular emphasis isgiven to maize, soya beans, potatoes, cotton, tobacco and oilseed rape.Traits that are emphasized are in particular increased defence of theplants against insects, arachnids, nematodes and slugs and snails byvirtue of toxins formed in the plants, in particular those formed in theplants by the genetic material from Bacillus thuringiensis (for exampleby the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2,Cry9c, Cry2Ab, Cry3Bb and CryiF and also combinations thereof) (referredto hereinbelow as “Bt plants”). Traits that are also particularlyemphasized are the increased defence of the plants against fungi,bacteria and viruses by systemic acquired resistance (SAR), systemin,phytoalexins, elicitors and resistance genes and correspondinglyexpressed proteins and toxins. Traits that are furthermore particularlyemphasized are the increased tolerance of the plants to certainherbicidally active compounds, for example imidazolinones,sulphonylureas, glyphosate or phosphinotricin (for example the “PAT”gene). The genes which impart the desired traits in question can also bepresent in combination with one another in the transgenic plants.Examples of “Bt plants” which may be mentioned are maize varieties,cotton varieties, soya bean varieties and potato varieties which aresold under the trade names YIELD GARD® (for example maize, cotton, soyabeans), KnockOut® (for example maize), StarLink® (for example maize),Bollgard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples ofherbicide-tolerant plants which may be mentioned are maize varieties,cotton varieties and soya bean varieties which are sold under the tradenames Roundup Ready® (tolerance to glyphosate, for example maize,cotton, soya bean), Liberty Link® (tolerance to phosphinotricin, forexample oilseed rape), IMI® (tolerance to imidazolinones) and STS®(tolerance to sulphonylureas, for example maize). Herbicide-resistantplants (plants bred in a conventional manner for herbicide tolerance)which may be mentioned include the varieties sold under the nameClearfield® (for example maize). Of course, these statements also applyto plant cultivars having these genetic traits or genetic traits stillto be developed, which plant cultivars will be developed and/or marketedin the future.

The plants listed can be treated according to the invention in aparticularly advantageous manner with the active compounds of thegeneral formula I according to the invention. The preferred rangesstated above for the active compounds also apply to the treatment ofthese plants. Particular emphasis is given to the treatment of plantswith the active compounds specifically mentioned in the present text.

In the field of household insecticides, the active compounds accordingto the invention are used alone or in combination with other suitableactive compounds, such as phosphoric esters, carbamates, pyrethroids,neonicotinoids, growth regulators or active compounds from other knownclasses of insecticides.

It has furthermore been found that the active compounds according to theinvention also have a strong insecticidal action against insects whichdestroy industrial materials.

The following insects may be mentioned as examples and as preferred—butwithout any limitation:

Method of Synthesizing the Compounds of the Invention

The compounds of formula (I) may be prepared by the application oradaptation of known methods (i.e. methods heretofore used or describedin the chemical literature): generally pyrazole ring formation followedwhere necessary by changing substituents; or methods described in one ormore of WO 98/28278 (U.S. Pat. No. 6,350,771), WO 87/03781 (U.S. Pat.No. 5,232,940) and EP 780 378 (U.S. Pat. No. 5,817,688). It will beappreciated by persons skilled in the art that, within aspect of theprocesses described; the order of the synthetic steps employed may bevaried and will depend inter alia on factors such as the nature of otherfunctional groups present in a particular substrate, the availability ofkey intermediates, and the protecting group strategy (if any) to beadopted (see e.g. “Protective Groups in Organic Synthesis (ThirdEdition)”, eds. Greene and Wuts, Wiley-Interscience, (1999)). Clearly,such factors will also influence the choice of reagents for use in thesaid synthetic steps.

In one embodiment of the invention, compounds of formula (I) wherein R₃is halomethyl are formed by reaction of the corresponding compounds offormula (I) in which R₃ is hydroxymethyl with halogenating reagents,more specifically brominating reagents such as a mixture of bromine orN-bromosuccinimide and triphenylphosphine, hydrobromic acid; orfluorinating reagents such as dimethylaminosulfur trifluoride,diethylaminosulfur trifluoride (DAST™) or bis(2-methoxyethyl)aminosulfurtrifluoride (Deoxofluor™). The reaction is usually performed in asolvent such as methylene chloride, chloroform and generally attemperatures between −100° C. and 40° C. A summary of such methods isfound in Comprehensive Organic Transformations, VCH Publishers, 1989, R.C. Larock, pp. 353-360.

In oneembodiment of the process, the reducing agent is L-Selectride™. Thereaction is usually performed in a solvent such as dialkyl ether (e.g.diethyl ether), tetrahydrofuran (THF) and generally at temperaturesbetween about −100° C. and about 40° C. A summary of such methods isfound in Comprehensive Organic Transformations, VCH Publishers, 1989, R.C. Larock, pp. 18-21.

In one embodiment ofthe process, the hydride agent is sodium borohydride. The reaction maybe performed in a solvent such as dialkyl ether (e.g. diethyl ether),tetrahydrofuran (THF), or a hydrocarbon (e.g. hexane or toluene) ormixtures thereof. A temperature of from about −100 to about the refluxtemperature of the solvent system is generally used. In one embodimentof the process, the temperature is between about 0° C. to about roomtemperature. A summary of such methods is found in Comprehensive OrganicTransformations, VCH Publishers, 1989, R. C. Larock, pp. 527-535.Compounds of formula (I) where R₃ is hydroxymethyl are novel,specifically when Z in this formula (I) is C—F, and constitute a furtherembodiment of the invention.

According to methods described in EP 780 378, intermediates of formula(I) wherein R₃ is formyl are formed by oxidative cleavage of the alkenemoiety of a compound of formula (II)

wherein R^(A) is selected from alkylcarbonyl, alkoxycarbonyl, cyano andnitro to form a compound of formula (IIa):

In another embodiment of the process, R^(A) is selected from C₁-C₄alkylcarbonyl, C₁-C₄ alkoxycarbonyl, cyano and nitro. Such atransformation is well known to those skilled in the art and can berealized for example with ozone, potassium permanganate, sodiummetaperiodate. The process may be carried out optionally in a solventsuch as methylene chloride, diethylether, chloroform and generally attemperatures between about −100 and about 100° C. A summary of suchmethods is found in Comprehensive Organic Transformations, VCHPublishers, 1989, R. C. Larock, pp. 595-596.

Compound of formula (II) may be prepared by dehydrohalogenation of acompound of formula (III) wherein “halo” represents halogen.

This can be effected by reaction of formula (III) compounds with basessuch as triethylamine, sodium hydroxide, potassium hydroxide, lithiumdiisopropylamide or 1,8-diazabicyclo-[5.4.0]-undec-7-ene (DBU). In oneembodiment of the process, the base is DBU. The reaction is carried outoptionally with an organic solvent such as dichloromethane,diethylether, tetrahydrofuran, or toluene, and generally between about−100 and about 100° C. depending on the base used. A summary of suchmethods is found in Comprehensive Organic Transformations, VCHPublishers, 1989, R. C. Larock, pp. 131-132.

Certain compounds of formula (II) and formula (III) are novel,specifically when Z in those formula (II) and (III) is C—F, and as suchconstitute a further embodiment of the invention. Compounds of formula(III) can be produced from compounds of formula (I), wherein R₃ is NH₂(formula (V)):

with an olefin of formula (IV):

The process is effected by reaction of a compound of formula (I),wherein R₃ is replaced by NH₂, in the presence of an alkylnitrite andCopper (II) halide, for example as described in J. Org. Chem., 1977, 42(14), 2431. Those skilled in the art will recognize this as a Meerweinarylation reaction, as reviewed in Org. React., 1976, 24, 225-259. Theprocess is generally carried out in a mixture of the olefin and a commonorganic solvent, such as acetonitrile and at a temperature from about−50 and about 100° C. In one embodiment of the process, the temperatureis about room temperature.

The compounds of formula (I) in which R₃ is replaced by NH₂ may beprepared by methods described in one or more of the following: WO94/21606, WO 93/06089, WO 87/03781; EP 295 117, EP 234 119; U.S. Pat.No. 5,232,940; or by methods known to the skilled in the art. Certaincompounds of formula (I) wherein R₃ is NH₂ are novel, specifically whenZ in this formula (I) is C—F, and as such constitute a furtherembodiment of the invention.

The synthesis of higher oxidation states of compounds of formula (I),i.e. compounds in which m is 1 or 2, can be achieved by oxidation of thecorresponding precursor compound of formula (Ibis).

wherein m is 0 or 1, using conventional oxidizers known in the art.

In one embodiment of the invention, a general reaction scheme forsynthesizing the compound of formula (I) can be described as follows:

In one embodiment of the present invention, compounds of formula (I)wherein R₃ is ethyl may be prepared by the reaction of the correspondingcompounds of formula (I) in which R₃ is replaced by vinyl by catalytichydrogenation, in the presence of a hydrogen source (for examplehydrogen gas, sodium hydride, lithium aluminum hydride or sodiumborohydride) and one or more catalytic metals (such as cobalt, nickel,palladium, platinum, ruthenium and rhodium). The reaction is generallyperformed in a solvent such as an alcohol (e.g. ethanol or methanol) andat temperatures between about −100° C. and about 200° C. A summary ofsuch methods is found in Comprehensive Organic Transformations, VCHPublishers, 1989, R. C. Larock, pp. 6-8.

Compounds of formula (I) wherein R₃ is replaced by vinyl may be preparedby reaction of the corresponding compounds of formula (I) in which R₃ isreplaced by halogen (e.g. chlorine, iodine or bromine), withvinyltributyltin, in the presence or absence of a base (for examplecesium fluoride or cesium carbonate) and with a palladium catalyst suchas tetrakis(triphenylphosphine)palladium. The reaction is generallyperformed in a solvent such an alcohol (e.g. ethanol), a dialkyl ether(e.g. diethyl ether), tetrahydrofuran (THF), or dioxane and attemperatures between about 10° C. and about 300° C. The reaction may beheated in a sealed tube in a microwave. This transformation is known asa Stille Cross-Coupling reaction and a summary of such methods is foundin “Metal-Catalyzed Cross Coupling Reactions”, Wiley-VCH publishers,1998, F. Diedrich and P. J. Stang, chapter 4 by T. N. Mitchell.

Ifappropriate, they can also be employed as intermediates or precursorsfor the synthesis of other active compounds.

In another embodiment this aspect of the invention, the compounds andcompositions of the invention are suitable for controlling pests such asinsects selected from the group consisting of Blattella germanica,Heliothis virescens, Leptinotarsa decemlineata, Tetramorium caespitumand combinations thereof.

In each aspect of the invention, the compounds and compositions of theinvention can be applied against a single pest or combinations thereof.

The composition containing the 1-aryl-5-alkyl pyrazole of the inventionmay be administered continuously, for treatment or prophylaxis, by knownmethods. Generally, a dose of from about 0.001 to about 50 mg per kg ofbody weight given as a single dose or in divided doses for a period offrom 1 to 5 days will be satisfactory but, of course, there can beinstances where higher or lower dosage ranges are indicated, and suchare within the scope of this invention. It is well within the routineskill of the practitioner to determine a particular dosing regimen for aspecific host and parasite.

In one treatment embodiment, the treatment is carried out so as toadminister to the animal, on a single occasion, a dose containingbetween about 0.001 and about 100 mg/kg of a 1-aryl-5-alkyl pyrazolecompound or between about 0.1 and about 200 μg/kg or about 100 μg/kg ofcompound. In another treatment embodiment, the treatment is via a directtopical administration such as a paste, pour-on, ready-to-use, spot-on,etc. type formulation. Higher amounts may be provided for very prolongedrelease in or on the body of the animal. In another treatmentembodiment, the amount of 1-aryl-5-alkyl pyrazole compound for birds andanimals which are small in size is greater than about 0.01 mg, and inanother embodiment for the treatment of small sized birds and animals,the amount of 1-aryl-5-alkyl pyrazole compound is between about 1 andabout 100 mg/kg of weight of animal.

The solutions according to the invention may be applied using any meansknown per se, e.g. using an applicator gun or a metering flask.

This method serves to cleanse the skin and the hairs of the animals byeliminating the parasites which are present thereon, as well as theirresidues and dejections. The result of this is that the animals are nolonger stressed by the parasites and their bites, this having positiveconsequences, for example on their growth and on the use of their foodration.

In one embodiment, a direct pour-on skin formulation according to thepresent invention can provide long-lasting and broad-spectrum efficacywhen the solution is applied to the animal's back, e.g. along the lineof the back at one or more points.

According to a first embodiment for administering direct pour-onformulations, the process comprises applying the solution to theanimals, the application being repeated every month or every two months.

According to a second embodiment for administering direct pour-onformulation, the process comprises applying the solution to livestockanimals before they arrive in the Feed Lot, it being possible for thisapplication to be the final one before the animals are slaughtered.

Obviously, the process may also consist in combining these twoembodiments, namely the first followed by the second.

In another embodiment, the compounds of the invention are administeredin spot-on formulations. While not wishing to be bound by theory, it isbelieved that these formulations work by dissolution of the dose in thenatural oils of the host's skin, fur or feathers. From there, the activeagent(s) distribute around the host's body through the sebaceous glandsof the skin. The therapeutic agent also remains in the sebaceous glands.Thus, the glands provide a natural reservoir for the active agent thatallows for the agent to be drained back out to the follicles to reapplyitself to the skin and hair. This, in turn, provides for longer timeperiods between application as well as eliminating the need tore-administer the dose after the host becomes wet because of rain,bathes, etc. The inventive formulation has the further advantage of notbeing directly deposited on the skin or fur, where self-grooming animalscould orally ingest the therapeutic agent, thereby becoming sick orpossibly interacting with other therapeutic agent being orallyadministered.

In one embodiment of the location of administration, a singleformulation containing the active agent in a substantially liquidcarrier and in a form which makes possible a single application, or anapplication repeated a small number of times, will be administered tothe animal over a localized region of the animal, e.g. between the twoshoulders. In one embodiment of the invention, the localized region hasa surface area of about 10 cm² or larger. In another embodiment of theinvention, the localized region has a surface are of between about 5 andabout 10 cm² area.

The invention is further described by the following non-limitingexamples which further illustrate the invention, and are not intended,nor should they be interpreted to, limit the scope of the invention.

EXAMPLES Preparation Examples

All temperatures are given in degrees Centigrade; room temperature means20 to 25° C. Reagents were purchased from commercial sources or preparedfollowing literature procedures.

Unless otherwise noted, purification by reverse phase columnchromatography was performed by dissolving the crude residue in a smallvolume of DMSO and filtering through a 0.45 micron (nylon disc) syringefilter. The solution was then purified on an HPLC purification systemmanaged by the Chromeleon™ software using a 50 mm Varian Dynamax HPLC21.4 mm Microsorb Guard-8 C8 column. The initial MeOH:H₂O solventmixture was selected as appropriate for the target compound. Thisinitial mixture was maintained for 0.5 minutes then changed by a lineargradient to a final concentration of 100% MeOH over 5 minutes. 100% MeOHwas maintained for 2 more minutes. Total run time was 8 minutes. Theresulting fractions were analyzed, combined as appropriate, and thenevaporated to provide purified material.

Proton and fluorine magnetic resonance (respectively 1H NMR and 19F NMR)spectra were recorded on a Varian INOVA NMR spectrometer [400 MHz (1H)and 377 MHz (19F)]. All spectra were determined in the solventsindicated. Chemical shifts are reported in ppm downfield oftetramethylsilane (TMS), referenced to the residual proton peak of therespective solvent peak for 1H NMR. Interproton coupling contants arereported in Hertz (Hz). LC-MS spectra were obtained using aThermofinnigan AQA MS ESI instrument, using a Phenomenex Aqua 5 micronC18 125A 50×4.60 mm column and a linear gradient from 55% MeOH: 1% CH₃CNin H₂O to 100% MeOH over 3 minutes. 100% MeOH was maintained for 2minutes. Melting points were determined using a Thomas Hoover capillarymelting point apparatus and are uncorrected.
